Greaseproof paper is a type of non-absorbent paper that can be used for various purposes in the kitchen like layering fragile foods such as pancakes, wrapping food for storage and lining cake tins. Whereas nonstick baking paper which sometimes also known as parchment paper has a non-stick coating that eliminates the need to grease the paper. Although it costs more than greaseproof paper, it is especially good for lining baking trays when you make meringues and other dishes with a high sugar content. These foods are likely to stick to greaseproof paper.
